Patented @ct. 2t, 1914.,

Toall whom it may concern Be it known that l, LAns C. PETERSON, acitizen of the United States, residing at Osage Cit in the county ofOsage and State of Khnsas; have invented. certain new and usefulImprovements in Loading Apparatus, of wh1ch the following is aspecification. a

The present invention involves certain improvements in loadin apparatus,and while designed particular y for agricultural purposes to facilitatethe loading of manure or t e like into carts or other vehicles, theapparatus may be readily employed in various industries where aconvenient and easily operable means for raising a load of material fromthe ground and delivering the same to an elevated point may be required.

Briefly s eaking, the invention comprises a suitable framework adaptedto rest upon the ground and embodying an inclined runway on which isadapted 'to travel a platform which is supported by telescopic armsconnected with the frame. Associated with said platform is a chutelocated at one end of the same and adapted to direct the materialsdumped from the platform to the point of deposit thereof.

In the drawings :-l igure 1 is a perspelp t e essential features of theinvention. Big. 2 is a front end view of the same..--Fig. 3 is theplatform in its lowered horizontal position in full lines, and raised todumping or delivery position in dotted lines.

The apparatus hereinafter set forth embodies especially certain featuresof improvement in the somewhat similar aparatus of m Letters Patent No.918,695 issued to me pril 20, 1909. o

Throughout the following detail description, and on the several figuresof the drawin s, similar parts are referred to by like re erencecharacters. I i

The framework of the apparatus of this invention may be said to com risethe spaced horizontal sills 1 connected at their opposite ends by thecross bars '2, the inc 1 ned runway consisting of the rails 3 connectedwith corresponding ends of the sills 1, and the vertical posts or bars 4connecting opposite corresponding ends of the sills 1 with the upperends of said rails 3. The

extending upwardly from the sills and terminating at medial points inthe lengths of the respective rails 3 to brace the latter efi'ectivelyunder the stress of the load that may be elevated by means of theplatform 8. The platform '8 has the edge members 9 to prevent materialthereon from being displaced except' endwise of theplatform. Telescopicarms *areemployed to support the platform. 8 and comprise the outertubular sections 10 and the inner sections 11, the latter being pivotedat the corners of the framework proximate to the points of connection ofthe members 1 and 4. The outer tubular sections 10 .of the telescopicarms are freely sl'idable with respect to the sections 11 so that in theoperation of the end of the platform 8 and is provided with flanges 12corresponding with the members 9 of the platform and adapted to lap overthe latter at the adjacent ends. At its free end the chute 12 carriesthe rollers ltwhioh are adapted to move along the rails 3 in an evidentmanner. V

The means for raising the platform 8 and its chute 12 comprises awinding shaft '15 supported by two of. the foremost bracing bars 7 ofthe framework. and having cables 16 adapted to wind at one end thereon,the opposite end of each cable extending to and being connected by hooks16' to the platform 8' and passing under a transverse bar 17, theopposite ends of which are attached to the members 10 of the telescopicarms. To the shaft 15 is secured an operating drum 18 about which acable 19 is adapted towind, said cable leading ofl' to any suitableactuating means or being connected with draft animals as desirable. Thecable 19 winds about the drum l8 in'-a direction opposite to that inwhich the cables 16 wind about the shaft 15 so that it will be obviousthat by forcibly unwinding the cable 19 from the drum 18 the cables 16will be wound on the shaft 15 thereby exerting an upward pull on the bar17 and raising the platform 8. To facilitate the movement of theplatform upwardly in respect to the runway of the framework, rollers 20are mounted upon the bar 17 as an axis and are adapted to freely travelalong the rails 3. The rollers 20 are maintained in their properpositions on the bar 17 by means of collars 21 at the inner sides of therollers, and by the members 10 at their outer sides, these two partsforming stops for the purpose mentioned.

During the operation of elevating the platformS the chute 12 movespivotally so that when the platform is near the top of the runway saidchute is practically at a right angle to the platform and remains insaid position until carried beyond the cross bar 5, whereupon the chutemoves down-' ward to the delivering inclined position illustrated indotted lines in Fig. 3, being supported in such position by means of thebrackets 22 which connect the upper ends of the rails 3 with the posts4, said brackets being of somewhat angular form.

The difference in the diameters of the shaft 15 and drum l8 permits ofthe operation of raising the platform 8 carrying a full load, at theexpense of a comparatively small amount of power. The return movement ofthe platform 8 is, of course, effected by gravitation of the same to itshorizontal position. It is preferred that the framework be constructedprimarily of angle iron of which mostof its parts are made, though anysuitable construction members may be utilized within the purview of theinvention.

In orderto hold the platform 8 in upright .out-of-the way position asshown in dotted lines in- Fig. 3, as when the apparatus is not beingused, a hook 23 is pivoted to the cross bar 5 and adapted to engage themember 17 on the arm sections 10. This hook is manually operable toengage member 17 but will gravitate out of engagement upon slightforward movement of the parts of the arm sections 10 and thus release"the platform permitting it to return to its normal position. Themembers .9 above mentioned are pivoted to the edges of the platform 8and springs 9 coact therewith to force said members 9 into the outwardlyinclined positions shown in Figs. 2 and 3, when the platform is lowered.When so arranged the members 9 form skids up which a scraper is adaptedto pass onto the platform'to dump its load preliminary to elevation ofthe latter. To the cables 16 are attached light ropes or connections 24:that lead through openings in the platform 8 to points of connection 24'with the members 9. Thus it is that when the platform 8 is raised slackin the cables 16 (see Fig. 4) is taken up and the tension on theconnections 24 causes the members 9 to be raised to approximatelyvertical POSI- tions at opposite sides of the load on the platform,whereby they will prevent the lateral displacement of the load in an0bvious manner. The springs 9 will restore the members 9 on thesubsequent movement of the platform to the ground. The cables 16 passover pulleys 5 on the bar 5, and the cable 19 under a pulley 6 on thebar 6, and draft animals may be hitched to a ring 2 on the bar 6,to pullthe apparatus from one field to another.

Having thus described the invention, what is claimed as new is 1. Inloading apparatus, the combination of a framework comprising inclinedrails, a platform adapted to receive a load thereon and to travel up therails, arms mounted on the framework and connected with the platform,means for raising the arms and thereby elevating the platform, movablymounted members at opposite edges of. the platform adapted to form skidsor inclines when the platform is in charging position, means connectingthe edge members with the said raising means whereby. the edge membersare caused to project upward from the platform to prevent displacementof the material on the latter during the operation of elevating thesame, and spring means for restoring the said edge members on return ofthe platform to its normal charging position.

2. In loading apparatus, a framework, a platform adapted to assume aposition on the ground adjacent to the framework, members pivoted toopposite edges of the platform and normally inclining downwardtherefrom, hoisting cables connected with the platform to raise the sameon the framework, and means intermediate the through the platform andconnected with said edge members.

In test mony whereof I affix my signature 1n presence of two wltnesses.
